It seems as if you'll often defeat enemies with a special move of some sort. There are a lot of food items to replenish health, if needed. As it is in M.A.M.E. now, it's listed as "not working," but graphically it seems to be pretty good(maybe an occasional screen flashing glitch). There's no sound though. Seems incredibly basic for the time it was released though.
